Effect of helicoverpa nuclear polyhedrosis virus (HNPV) on different life stages of Helicoverpa armigera (Lepidoptera:Noctuidae) uri icon

abstract

  • Helicoverpa armigera Hubner, chickpea pod borer is aserious pest of legumes, cotton and vegetables in the Indiansubcontinent. Widespread appearance of resistance tochemical insecticides has stimulated efforts to developalternative control methods including the use of insectviruses against this pest. Several workers proved theeffectiveness of HNPV under field conditions in controllingH. armigera in chickpea (Dhamdhere and Khaire, 1986,Jayaraj et al., 1987, Cowgill and Bhagawat, 1996). However,there were several gaps in the utilization of HNPV and itsaffects on the life stages of H. armigera. This paper discusses the quantification of various ill effects of HNPV on Helicoverpa life stages under laboratory and the effect of Robin Blue as ultraviolet protectant with NPV in enhancing its persistence in chickpea ecosystem
